| - The structural design of the water shield began by considering a 1.5m thick slice of the 9m roof span. There was assumed to be no live load; and a 3 m water dead load acting over the entire roof. The maximum moment was then found to calculate the maximum tensile stress in this roof beam. This tensile stress was used to find the stress in the membrane material.

| - Due to possible construction difficulties of the corrugated modules, a modified non-corrugated design was considered (pdf page 4). This design called for two layers of modules with offset joints. | - Due to possible construction difficulties of the corrugated modules, a modified non-corrugated design was considered (pdf page 4).
